MACHINE FORv CUTTING AND SWAGING BALE TIES.

appiiicatinn filed nine` 14, 1922. seriai No. 568,305.

cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Machines for Cutting and Swaging Bale Ties; and we do hereby declare the following to b e a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it. appertains to make and usethe same.

This invention relates to amachine for straightening, swaging and cutting wires into predetermined lengths, and has for its object to improve the construction of somewhat similar machines that have been heretofore proposed.

Vith these and other objects in view, the invention consists in the novel details of construction, and combinations of parts more fully hereinafter.disclosed and particularly pointed out in the claims.

Referring to the accompanyin drawings forming a part of this speci cation, in which like numerals designate Alike parts in all the views:

Figure 1 is a diagrammatic side elevational view, partly in section, of a machine made in accordance .with this invention;

Figure 2 is a fragmentary detail view, in plan, showing how the wire receiving channel may be opened;

Figure 3 .is a cross sectional view of the wire receiving channel and its supporting parts; Y n

Figure 4 is a face view of the pedestal portion of the machine, indicating the cutting andswaging dies and tlfeir eo-acting parts;

Figure 5 is a plan view of the Wire straightening and feeding portion of the machine;

cates' a supporting base mounted on the frames 5 and G. Carried by the base 4 are a plurality of frame members 7, 8, 9, 10

and 11 supporting the wirev guide or runway 12 of an inverted U-shape having the slidably removable bottom member 13 sup- Y ported by the arms 14 with which'the memit will be apparent that when the lever 25 strikes the toe 26 of said lever 20, its end "21 will swing in a counter-clockwise direction, as seen in Figure 2, and carry with it said bottom 13. The latter will thus move endwise and away from the runway 12, be-

ing guided in its movements by the members 15.

27 represents a power pulley rigid with the shaft 28 carrying the bevel gear 29 meshing with the gear 30, rigid with the shaft 3l carrying the feed roll 32 and turning by suitable' connections not shown the lcompanion feed roll 33. Said shaft 28 also carries the pulley 35 over which passes the belt 3G, and the latter imparts rotation to the pulley 3T rigid with the wire straightener 38. of well known. form, mounted in the bearings 39 and 40. The wire 41 to be straightened, deformed, and severed, is fed,

` from a coil not shown, through the pulleyT 37, straightener 38 and between the feed rolls 32 and 33, which exert a pull on said wire and serve to push the Same through the channel or runway 12 until its extreme end 42 strikes the plunger rod 43 and pushes the same toward the left as seen in Figure 1.

When this happens, a predetermined length of straight wire has entered said channel 12 and its end'is ready to be deformed and severed in the manner now to be disclosed.

Said plunger 43 has attached to its outer end the lug to which one end of a wire 45 is secured, which carries a stop 4G, and between this stop and the frame member 11 is located a spring which is compressed when the wire 45 is pulled on by' the stop 46. The pulling of the wire 45 by said stop turns the bell crank 48 on its pivot 49, which lifts the arm 5() and the rod 5l connected thereto. Said rod is joined to the slidable bar 52 mounted in the housing 53, and its lower end normally lies in the path of a clutch member 7l.

That is to say, the tly wheel Tt) is rigid with the power shaft' :2H and continuously turns therewith while the cani 5t) is loose on said shaftand only turns when coupled to Said fly wheel by the lspring controlled clutch member 7l entering a notch 72 in said fly wheel as best illustrated in Figure (3. 'hen said cam .39 and clutch member 7l are turning with said ily wheel Tt), the path of said clutch '71 being crossed by said har 52, the beveled outer end 71S of said clutch will strike the bar 52 and the cam will be disengaged from the tly wheel after one rotation has taken place. ()u the other hand, when the bar raised out. of the path of theclutch '71 in the manner disclosed, the spring 74 will cause said clutch to engage the fly wheel and the cam will again be given a single revolution.

livoted atl 57 to the face 55 of the pedestal l is the lever 25 above mentioned, whose lower end carries a roller 5S which is moved by the cam 5t). and thus is the upper end of the lever carrying the cutting and swaging die (St) thrown to the left', as seen in Figure 4. The wire 4l is fed by the rollers 32 and 33 across the path of movement of said die 60, 'and over the face of the anvil 61 rigid with said pedestal l, all as will be clear from Figures l, 4 and 7. A .f

The parts are so timed and adjusted that when the end 42 of the wire 41 strikes the plunger 43 as above described, the wire 45 will be pulled on, the bell crank arm 5t) will be lifted, which will lift the rod 52 out of the path ofthe clutch member 7l, and said cam 59 will be joined to and rotate with said fly wheel and shaft 28. The rotation of the cam 59 actuates the lever 25 and swaging die G0 to cut the wire 4l, and to deform its end by placing a notch or other depression therein as best seen in Figure 8. At the same time, the swaging and cutting action takes place, the lever 25 strikes thel toe 26, (see Figure 2) and opens the. bottom of the channel l2 to permit the severed wire to fall out. -The springs 76 return said bottom for the next wire.

The purpose of this machine is to first straighten wire material which is sold in large coils, and to swage their ends as illustrated in Figure 8, and then cut them into Apredetermined lengths in order that they may be used in the now well known wire tying machines which employ such swaged wires in the banding of boxes and other packages.

The operation of the machine will be clear from the foregoing, but may be briefiy summarized as follows: The wire ll is brought to the straightener 3o from the coil ot' wire not shown. it ispassed between feed rollers 15:2 and :lil over the anvil tl and swaging die member carried thereby, whence it is passed into the rea'eiring channel 1:2, where its extreme end 42 strikes the plunger lil which actuales the wire 45, bell crank 4H. and pulls up on the rod 52 lying in the pathot' the clutch Tl. `\\"itlulrawal of the said rod o2 from the. clutch 7l causes said Aclutch 7l to connect the actuating cam 59 with the continuously rotating ily wheel 70, and -to actuate the louer end of the lever 25, which is pivoted to the face .35 of the pedestal l. at the point 57, .see Figure 4. rIhe upper extreme cud of .the lever 25 carries another member t3() of the cutting and swaging dies, which more in the arm of a circle and intersect the'path of the straightened and fed wire 41.

lt thus results that when the cam 5t) actuates the lever 25, the die member carried thereby forces the said wire 4l against the companion die. members carried by the anvil (31, and places the notch 75. see Figure 8, in the wire, while at the same time cuts otf the desired predetermined length of the wirefall as will be clear from Figure 7.

A fter a predetermined length of the wire 41 has been thus cut oilf, it is dropped from the channel ft2 by reason of the bottom 18 being withdrawn from said channel, all in the manner above described.

lt is an important feature of this invention that the anvil G1 is placed in the are of the circle traversed by the die member G0 and at a distance of about 45o from a verticle plane passing through the pivot 57, for by so placing this said anvil, the severed wire 4l readily rolls off or falls off the surface of the anvil and drops from the channel l2. lVere the said anvilplaced in a vertical position, or say 90C from the said vertical plane above mentioned, the wires would be caught on the surface of said anvil,

and would thus clog the machine. 'On the,

other hand, if the anvil were placed in a horizontal position, or with its swaging surface in said vertical plane, the swaging ac tion ot' the die 60 could not act upon the wires as efficiently as is the case when the anvil is placed as illustrated in Figure 4. It is a further important feature of the invention that the cutting member of the die G0 moves in contact with the face of the pedestal l. for such location readily permits the wire to be efliciently sheared or cut in two parts, and it is an additional feature of the invention that the swaging member cated a -short distance from the end otl said wire. thus causing said end to constitute aholding portion or head. as will be readily understotal. Further,` this location ot' the swaging member ot' the die and the forming ot said swag-ing member integral with the cutting membei` causes the swaging member to strike tlat against the anvil tilV simultaneously with the severing action of the cutting member.
